A new supercomputer (Summit) built by IBM and Nvidia (https://gizmodo.com/the-world-s-most-powerful...is-an-absolute-1826679256) was annouced by this artilcle. Lets say that all of WCG computing could be done with just 2 of the 200 petaflops this computer can do. It could do all of WCG computer needs with just 1% of its time. By my calculations that would be just 14.4 minutes each day. I think I am being generous in assuming 2 petaflops for WCG. The article ends by stating a supercomputer with 5 times more power is just around the corner(2020) or less than 3 minutes of its time to duplicate all of WCG's effort.

Of course the real problem is getting all the software to run on it.

I don’t know if it’s an apples to apples comparison. Since it uses a large number of GPU’s to accelerate computing. When we have a GPU project to run, WCG is many multiples faster than it currently is. So, it’s more about that software you’re able to run than anything else.
Also this system uses 13 megawatts of elecctricity which is a huge amount. WCG is much more environmentally friendly using electricity that would for the most part otherwise be wasted, except for dedicated crunching machines. Still it’s an incredible machine and it would be nice to see it in action. |

It was nice to complete a WU in minutes instead of hours when we had gpu projects. Wish we had more projects for gpu but must have been hard to program for it. Otherwise we would have more projects using the power of the gpu.

Crunching for humanity since 2007!

GPUs need highly parallel and linear work. Wide data sets and little branching work seem to work well. The many atoms in protein structures seem to crunch hard along with linear math projects. Not sure how WCG projects compare with that.  |

Here's a good audio talk about the new system. Some talking points I found interesting:
It was said that only 5-10% of the computing power comes from the IBM Power 9 CPU's which would mean 90-95% of maximum performance comes from the Nvidia GPU cluster. Also said that about 15% of the code they run uses the single precision GPU portion of the computer. Also the 13Mw is 1/2 the power of the previous supercomputer they had, Titan. https://www.top500.org/news/doe-launches-summ...d-to-reclaim-top500-lead/ |

Well, no...on those big machines, you can put lots of VM...which can generate results from their CPU & GPU, while emulating PC + Win or PC + Mac or ARM + Android...& you can still get results from CPU Power9 + GPU nVidia, even though you don't use GPU on WCG... But it all depends how well VM is written. Also, BIG NO...WCG is not efficient, by a BIG MARGIN! There are 750k users on WCG of which 50% are active, which use power of average of 200Wh (that is only one computer, though I run 4 of them...& that is to say they don't do GPU crunching at all). So the calc goes: 750.000 x 50% x 200Wh = 75.000.000Wh or 75MWh So WCG is not power efficient at all...it's only "charitable"!  |
